o all rwhom it may conoerm 't v Be it known that I, Fnnn Ems, a citizenci' the United States, residing at-St, Louis, the State oiMissour haveinvented ceriilfn Im, irovements in olddowns, of which ,the following4description, in connection Y th the accompanying drawings, is aspecication, like reference characters on the "2f-*drawings indicatinglike parts in the several l figures. 1 f

,Ty This invention relatesl to hold-down devices for use in connectionwith bed lasting y machines, such, for exemple, as the I welli-lm'ownkcommercial Ideal lasting machine lo which is shown in the United Statespatent 'izto Grandy No. 552,834, to which reference muy be had for edescription off the machine in general. v A

.he present' invention is embodied in an improved form of hold-downfoot. Prefer- "nbly andes shown, the hold-down foot com- -priseseplatewhich is oi substantially the shapeofithe toe portion of an innersoleand sndcpted to iit closely egeinstl the rear face ofthe raised lip orrib which exists on the eiinersole of e, Welt shoe., saill plete beingga :,tpted toisustain the rib against the lateral bressure of the. to@lsstin wipers as ,they lare operated `for working t up er into the 39angle formed by the feather and rib of the innersole.

As another feature of lthe inventiomthe yrib engaging portion of thefootfplete is 'formed by the edge of the plate only which iscshown asturnedv downwardly at an angle to the plane of the sole to form a flangeand is dressed 0H so als to rest evenly against the' face of theinnersole, preferably with a substential space between the face oftheinnersole and .the body of the plate. This formation of the hold-downfoot plate adopts it l for use also as a feather clamp. In such use itis positioned first forwardly of, or outi side 5f, the rib and uponthefeather edge of downorkthe lestl so as' to redtlce danger of thefeether'being ece, by 'the Wi' i rs .in their pward'mov" n a'nd lityaway from the' stntally rigid, as com wed Wlththe innersole where itmaintains the featherv thinness of the down-turned edge or flangeportion of the plate in engagement with the Alfeether enables the wipersto be forced in over the edge of the last and over the feather of theinnersole sufficiently Vfar to hold firmly the upper in lasted positionbefore the hold-down plate is withdrawn from engagement with thefeather. When this, is donc,

the wipers may he advanced farthertocrowd the upper into the angle andinto position to be secured hy Wiring-or otherwise. When the plete 'aswithdrawn from the feather and prior to this further movement of thewipers theplate may be again positioned behind the lnnersole rib to Suport it during the final inward movement'ov the Wipers.

As l am advised, it is new with me to provide a, hold-down foot which isconstructed and arranged so tha-tit can be used alternatively orsuccessively outside of e welt innersol'e lip orrib as a feather clumpextend` in around the curved end of the toe or insi e the rib as anabutment to resist lateral pressure aga/inst the rib at one or bothsides as well as at the tip of the toeend of the innersole.

` The outside edge contour of the hold-down and another advantageous useof this foot is as a binding wire seat crease former in. cooperationwith the wipers. In this use thefoot is positioned upon the feather justoutside the innersole rib and, it being thin, v the wipers are advancedand mold the upper against the outer faceof ,the foot to produce the'.wire segst crosse, The foot .being sul tre rib of the nner'sole, thecrea, is more definitely forme then ithles heretofore been formed betweenthe Wipers and the rib. The vwipers are thenfbacked nwe slightlyfrom the .crease thns formed to a low the binding wire to bepla'eed i,the seat for it and to ermit the Afoot to be withdrawn from the. estherjandppsitioned inside the rib where it may serve es an abutment for therib. The wip# ers calin then be agam edvenced to engage the :vire andpress it into its sent crease end there after, and here is tine of theimportant ad- ,vantages for this` feature Yof the invention, to forcethe seat crease Ainwardly toward and against the innersole rib and thussubstan- .tiall tighten the upper. This action is particu arlyadvantageous atthe sides of the tip of the toe, or the corners of thetoe, where it is most diicult to overwork the upper without wrinkles'orlooseness.

As a further feature of this invention, with which may or may not beused the foregoing features, the foot plate which constitutes thepressing member of the hold-down is supported 'for lateral movements ofadjustment or adaptation to the work on an arm which is movable over thebottom of a shoe sustained in position to bellasted in the machine.There 1s a pivotal connection between the foot plate and the supportingarm which is preferably located so that `it will be over substantiallythe center of curvature of the toe end of the innersolewhen the footvplate isfin operative position. By this ad- )ustable mounting` the footplate may be 25 swung toward one side or the other side of itssupporting arm to enable it to fit innersoles for right and left crookedlasts having toes of approximately symmetrical curvature. It is mostimportant that the foot plate form an abutment for the innersole rib atthe outer side of the toe because it is at this side of the toe thatmost difficulty is exiIiierienced in properly lastin f the upper rmlyagainst the rib. There ore, while'the foot plate may most advanta eouslybe made to fit the shoe exactly and e changed for different sizes of thesame style of last, the same foot plate, mounted 'as her'ein described,may--be used with 'very satisfactory results for larger shoes than itaccurately fits, this being donev by positioning and swinging it overagainst the rib at the outer side of the toe of the right or left shoewhich happens to be in the machine. `To make thisclear thisuse ofthe-holdvdown foot is illustrated in the accompanying drawings. t

This invention is particularly advantageous when used with machines ofthe Ideal type abovereferred to. in which the alinement of'the toe andheel heads and of the wipers carried thereby is fixed, and conse-(fluently the longitudinal median line of the orepartof a last which hasconsiderable swing will extend at a substantial angle to the lineconnecting the center of the toe head, or the toe wipers, with thecenter of the heel head, or the heel seat wipers, the said median lig'neextending to one side of the line joining the end centersl of the lastfor a right shoe and to the other side for a left shoe. Means forlimiting the movement of the plate about its pivot is preferabl providedand may jconveny iently take t e form of a slot and pin connection, theslot being formed in the plate and being struck from the pivot of theplate as a center and a headed pin being passed through the slot andsecured to the sulpporting arm to co-act with the ends oft e slot forlimiting the movement of the plate in either direction.

These and other features of the invention y/will ap ear more fully fromthe following detailed) description in connection with the accompanyingdrawing, and will then be more definitely pointed out in the claims.

Figure 1 is a plan view of a lasting machine of thee/Ideal type asdisclosed inthe patent above referred to providd with the preferredembodiment of the invention; Fig. 2 is a perspective view, partly insection, showing the manner of attaching the hold-down foot to thehold-down arm, the foot and its supporting arm being shown by full linesdetached from their swinging carrier, and by dotted lines in operativep0. sition; Fig. 3 is a longitudinal section of theforepart of a shoe'showing in side elevation the hold-down foot applied thereto:

In Fig 1 which is a plan view of a ma- 90` chine of the Ideal type, theheel and toe A heads are represented at A and B` respectively, thelongitudinal axis of the machine passing centrally through them both.The character 2 indicates the ySwingin carrier by which the hold-downfoot 30 and its supporting arm 20 are moved over' the bottom of the shoesustained in position to l s 1'usted in the machine. The hold-downcarrier is mounted to swing on a post 1 and has a 100 vertical movementwith the post. This l post constitutesthe operating means for thehold-down and with 1t is connected a usual actuating treadle and areturn spring, and preferably also a lockin latch as. shown for examplein British atent No. 19,512, 1911. The hold-down foot 30 which isconnected to the arm by complemental formation of any suitable characterpermitting lateral Yswinging movement ofthe ffoot about pivot 32. Suchmovement is limited, and the foot plate is further secured to,the\ arm20, by a headed stud 36l and curved slot 34 connection between the armand the plate in the rear of the pivot 32, the slot lltbeing curved inan arc about said i'vot 32.-

Y The hold-down foot is shap to lit closely against the innersole rib atthe tip of the toe and is contoured to form an abut-'1. ment for theinner face of the rib both at 130 the tip and' at one or hath sidesofthe tip of the toe for supporting'said rib a 'list the action of thellasting wipers. The olddown foot is advantageously hollowed on its workengaging lower face thus affording i a concentrated bearing of its edgeupon the innersole closely adjacent to the innersole rib and unaffectedby irregularities in-the surface of the middle portion f the inner- Isole. As shown, this foot comprises a plate to formk a down turnedflange 31.

its ges bent' at the front end and slidles is formation permits the footplate to be applied either with its bearing fla-ngeinside the innersolerib as shown in the drawings or outside of saidrib Where it will pressdown upon theffeather of the innersole to prevent the 'feather frombeing lifted by the wipers. if the shoeds large for the foot plate, aswill in practice often be the caste,

the foot plate is made to abut against the rib at the tip of the toe andis swung into engagement with the rib at the outer side of the toe, asshown in the drawings, where the rib most requires support. In Fig. 1the foot plate 30 is shown in the position it would assume upon a rightshoe, the right shoe being shown in full lines in that figure in whichthe swing of the last is indicated by the line @1w-R which is thelongitudinal median line. of the forcpart extended. In dotted lines inthe same figure is represented the outline of the leftshoe, thelongitudinal median line of the forepart of which extends in thedirection of mv-L. It will be seen that the line .fr-R is inclinedtoward the axis from the other side and that considerable movement ofthe plate 30 is required to enable it to fit closely the toe portion ofa right or left shoe where the swing of the last is considerable. Toprovide this movement the plate 30 is pivoted to the arm 20 at 32, whichpoint is substantially at the center of curvature of the extreme toeportion of the plate. The plate 3() beingl freely pivoted at this pointautomatically assumes ay position against the rear face of the rib ofthe innersole when pushed forward against it by rotation of the earrier2about the vertical axis 1. The arm 20 which supports the hold-down platef3() is perferably resilient and the stud 4 by :which it is pivotallyattached to the arm 2 has a, roughened head G, Fig. 3, which is adaptedto engage the innersole when the engagement of the piate 30 1with theshoe has caused the arm 20 to yield. The stud 4 is flattened on itssides at 8 and maintained in fixed position in a hole in the aim Qrhy aspring-heldpin it) which is forced outwardly into a hole l in the stud.The stud is passed through a plate 14 havin lips 16 bent up at the edgesthereof. The arm 20 is provided at one end with a hole 22 having an openslot Q4 leading therefrom and. is assembled upon the end of thehold-down arm by pushing the slotted end upon the stud in the directionof the flattened sides of the stud until the stud rests in thi` opening22 when the arm 20 may be rotated about the stud. The lips 16 of theplate 14 are arranged to rest against opposite sidesfof the arm 20 andby reason of the tapered formation of the arm 20, Fig. 1, it

cannot be pulled from the stud even when in line with the flattenedsides thereof until it has been sprung over the lips 16.

For different styles of shoes differenthold-down feet may be provided,the construction shown providing means for readily detaching one footand its arm 20 and attaching another. T effect this the operator hasonly to insert a pointed instrument between thev plate 14 and the springarm 20 and separate them vsufiiciently to disengage the lips 16 from thearm 20 so that the plate 14 andparm 20 may be swung relatively to eachother about the stud. The arm 20 may then be detaehed by rotating itinto alinement with the hold-down a-rrn, Fig. 2,.and pulling itoutwardly in the direction of said arm, the flattened sides of the studthen permitting it to pass through the slot 24 of the arm 20. Otherhold-down feet may be attached to the hold-down arm by reversing themovements described for. removing the foot.

The use and operation of the described embodiment of the invention maybe readily understood by those skilled in the art with out furtherdescription, and it is also apparent that various modifications of thedevice as described may be made without departing from the invention.
